cilia reddish-ochreous-brown, becoming whitish-ochreous at tips, on anal 
angle dark grey. Hindwings whitish, spotted with grey except posteriorly, 
apex reddish ; cilia whitish, with an obscure grey basal line. 
I am compelled to separate this species from C. eacessana on account of 
the structural difference in the antenne of the male; otherwise I should 
certainly have regarded it as a mere variety. It is constantly much 
smaller than the average of that species, but C. excessana is occasionally 
quite as small; it is also much redder, and the hindwings are more 
clearly whitish, but these points are quite indefinable, and would not be 
sufficient for demarcation ; moreover I conceive that the diminished size and 
the reddish colouring of both larva and imago are the direct effect of the 
peculiar foodplant. But the antenne of the male are in C. eacessana 
tolerably filiform, the joints hardly dilated, the ciliations not longer than the 
width of the joints; whilst in C. alopecana they are conspicuously serrate, 
the joints almost triangular, and the ciliations much longer, fully twice the 
greatest width of the joints. These differences are quite constant, and must 
be regarded as sufficient. 
Larva 16-legged, moderate, cylindrical, somewhat tapering at both ends; 
variable, yellowish to ochreous-fuscous; segmental incisions and some- 
times sides ochreous-carmine ; spots large, pale, in some lights whitish ; 
head and second segment ochreous-fuscous. Feeds in spun shoots and 
between joined leaves of Phyllocladus alpinus (Conifere),in January. Pupa 
in the same position. 
I took two specimens in the forests on the Bealey River (2,100 feet) in 
January, and at the same time found larve feeding, from which I bred: 
three more specimens in February. 
CONCHYLIDIDA. 
This form of the name, which is orthographically the more correct, 
should be substituted for Conchylide. 
Hererocrossa, Moyr. 
The pectination of the lower median vein of the hindwings in this genus 
is, so far as I can ascertain, confined to the female; the male does not 
possess any trace of it. I had originally supposed that this was due to - 
denudation in the case of the two or three male specimens which I possessed, 
but having since acquired more material, I find it to be the normal strueture. 
I think however that the point is not less valuable for generic separation ; 
in the female of Paramorpha, which is the nearest allied genus, this well- 
developed pecten does not exist.
